关闭键盘 - iOS 7中的多个UITextFields [英] Dismiss The Keyboard - Multiple UITextFields in iOS 7

问题描述

下面你会找到我的.h&我的主viewcontroller的.m文件。

我有3个问题。

1。）因为我有多个uitextfields，我是否必须设置每个用自己的resignFirstResponder声明？ 2.）我会用哪种方法做到这一点？ 3.）我的语法是否适合辞职第一响应者？

当用户点击字段时，如果我可以解除键盘，那将是非常好的点击返回键！

我知道之前已经被问过并回答过，但说实话，我仍然有点困惑。

我正在使用故事板，使用XCode 5和iOS 7.

====== =======================

.h文件

  @interface ViewController：UIViewController< UITextFieldDelegate，UITableViewDelegate，UITableViewDataSource> 
 
 @property（弱，非原子）IBOutlet UITextField * danceDate; 
 @property（弱，非原子）IBOutlet UITextField * dancePlace; 
 @property（弱，非原子）IBOutlet UITextField * danceTerminal; 
 @property（弱，非原子）IBOutlet UITextField * danceGate; 
  

.m文件

  #importViewController.h
 
 @interface ViewController（）
 
 @end 
 
 @implementation ViewController 
 
  - （void）viewDidLoad 
 {
 [super viewDidLoad]; 
 
 [self retrieveFromParse]; 
 
 self.tableView.dataSource = self; 
 self.tableView.delegate = self; 
 self.navigationItem.rightBarButtonItem = self.editButtonItem; 
 
 // SET DELEGATE HERE 
 // 
 //如果我取消注释其中一行，我会收到错误。 
 // 
 // _dancePlace.delegate = self; 
 // dancePlace.delegate = self; 
 // dancePlace = self; 
 
} 
 
  - （void）textFieldDidBeginEditing：（UITextField *）textField 
 {
 
} 
 
 - （BOOL）textFieldShouldReturn：（UITextField *）textField 
 {
 [textField resignFirstResponder]; 
 
返回YES; 
} 
 
 
  - （BOOL）textFieldShouldReturn：（UITextField *）textField 
 {
返回YES; 
} 
  

解决方案

辞去textField：
所有textField.delegate都应设置为ViewController的对象。
然后实现下面的委托方法。

   - （BOOL）textFieldShouldReturn：（UITextField *）textField {
 [textField resignFirstResponder]; 
返回YES; 
} 
  

要点击视图关闭键盘：
添加点按对ViewController.view的手势如下：

  //声明一个属性来存储当前的响应者
 @property（ nonatomic，assign）id currentResponder; 
 
 
 //在viewDidLoad中：
 
 UITapGestureRecognizer * singleTap = [[UITapGestureRecognizer alloc] initWithTarget：self action：@selector（resignOnTap :)]; 
 [singleTap setNumberOfTapsRequired：1]; 
 [singleTap setNumberOfTouchesRequired：1]; 
 [self.view addGestureRecognizer：singleTap]; 
 [singleTap release]; 
 
 //实现以下委托方法：
 
  - （void）textFieldDidBeginEditing：（UITextField *）textField {
 self.currentResponder = textField; 
} 
 
 //实施resignOnTap：
 
  - （无效）resignOnTap：（id）iSender {
 [self.currentResponder resignFirstResponder]; 
} 
 //丢失了;通话结束后 - > [self.currentResponder resignFirstResponder] 
 //也在textFieldDidEndEditing中设置self.currentResponder = nil; 
  

below you'll find my .h & .m files for my primary viewcontroller.

I have 3 questions.

1.) Because I have multiple uitextfields, do I have to set each with their own resignFirstResponder statement ? and 2.) where would I do that, in what method ? 3.) Is my syntax right for resigning the first responder ?

Also it would be really nice if I could dismiss the keyboard when the user clicks out of the field NOT on hitting the return key!

I know this has been asked and answered before, but to be honest with you i'm still a little confused as to what goes where.

I'm using storyboards, with XCode 5, and iOS 7.

=============================

.h file

@interface ViewController : UIViewController <UITextFieldDelegate,UITableViewDelegate,UITableViewDataSource>

@property (weak, nonatomic) IBOutlet UITextField *danceDate;
@property (weak, nonatomic) IBOutlet UITextField *dancePlace;
@property (weak, nonatomic) IBOutlet UITextField *danceTerminal;
@property (weak, nonatomic) IBOutlet UITextField *danceGate;

.m file

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];

    [self retrieveFromParse];

    self.tableView.dataSource = self;
    self.tableView.delegate = self;
    self.navigationItem.rightBarButtonItem = self.editButtonItem;

    // SET DELEGATE HERE
    //
    // if I uncomment 1 of these lines, i'll get an error.
    //
    // _dancePlace.delegate = self; 
    // dancePlace.delegate = self; 
    // dancePlace = self; 

}

- (void)textFieldDidBeginEditing:(UITextField *)textField
{

}

-(BOOL) textFieldShouldReturn: (UITextField *) textField
{
    [textField resignFirstResponder];

    return YES;
}


-(BOOL) textFieldShouldReturn: (UITextField *) textField
{
    return YES;
}

解决方案

Resigning the textField: All your textField.delegate should be set as ViewController's object. And then implement the below delegate method.

-(BOOL) textFieldShouldReturn: (UITextField *) textField {
[textField resignFirstResponder];
    return YES;
}

To dismiss Keyboard on tap of the View: Add a Tap gesture to your ViewController.view as follows:

//declare a property to store your current responder
@property (nonatomic, assign) id currentResponder;


//in viewDidLoad:

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(resignOnTap:)];
    [singleTap setNumberOfTapsRequired:1];
    [singleTap setNumberOfTouchesRequired:1];
    [self.view addGestureRecognizer:singleTap];
    [singleTap release];

//Implement the below delegate method:

- (void)textFieldDidBeginEditing:(UITextField *)textField {
    self.currentResponder = textField;
}

//Implement resignOnTap:

- (void)resignOnTap:(id)iSender {
    [self.currentResponder resignFirstResponder];
}
// was missing ; after the call --> [self.currentResponder resignFirstResponder]
    // also in textFieldDidEndEditing set self.currentResponder = nil;
